FOLDING WRITING-DESK.

Specification of Letters Patent.

Application filed June 3, 1908.

Patented July 20, 1909.

Serial No. 436,497.

To all whom it may concern:

Be it known that I, CHRISTIAN Morin, instructor, a subject of the Kingof Prussia and German Emperor, residing at Uetersen, in the Province ofSchleswig-Holstein, in the Kingdom of Prussia and German Empire, haveinvented certain new and useful improvements in Folding Writing-Desks,of which the following is a specification.

The present invention refers to a folding w 'iting desk which consistsof three boards and which can be placed in such a manner that not onlyan inclined surface is produced but also an inclined back is provided atthe top end of this inclined surface, against which back books, patternsor the like may be placed. The single boards of the desk can be foldedentirely together,

when the desk is not in use, so that the whole apparatus is only as thicas the three boards together and requires very little space and can beput away in any corner.

In the accompanying drawing the new folding writing desk is illustrated,Figure 1 showing the three boards folded together, Fig. 2 the threeboards opened ready for use, Fig. 3 the plate hinge required forsecuring the supporting board.

To a board a suitably made of several thin boards glued together isattached by means of hinges (Z a board I) of about half the size ofboard a, so that this board projects with its front edge somewhatbeyondv board a. For this purpose board a is beveled at its upper edgeand this bevel determines the incline of board 6, as this board willrest with its projecting edge against the said bevel. In this position,Fig. 2, the lower edge of board I) must be equal with the under surfaceof board a. ()n the under side of heard u secured by means of hinges e asupporting board 0. For increasing the supporting surface of thissupporting board 0 it is provided with a strip h.

On the upper surface of board a and at a short distance from the upperedge is provided a rail f of any suitable section, for which rail agroove is provided in board I). This rail f has the purpose to preventthe books or the like leaned against the inclined board I) from slippingdown, whereas on the contrary they will rest against the said rail f.

For securing the supporting board in the position shown in Fig. 2 aspecial form of hinge is provided, this consists of the two plates 7.:and g, moving like a hinge toward each other, of which plate 70 is letinto the undersurface of board (1 whereas plate 9 likewise sunk into theunderside of plate a will when opened into the position shown in Fig. 2give the support a steady stop and prevent it from folding back. Part iscan be secured by means of screws or in any other manner to board a. Incase the desk has too great an incline when the supporting board isopened, the said supporting board may be simply turned down on itshinges as shown in Fig. 1 and the board I) be left turned up as shown inFig. 2.

Having now described my invention what I claim and desire to secure byLetters Patent of the United States is:

A. folding writing desk consisting of three boards hinged together, thetop board projecting with its edge somewhat beyond the writing board,said writing board beveled at this edge against which bevel the topboard rests when opened, a supporting board hinged to the underside ofthe writing board, and means for securing such supporting board in itssupporting position as described.

ln testimony whereof I have hereunto set my hand in the presence of twoWitnesses.
